Cylinder refill and exchange covers the small-tank side of the propane business: the 20 lb bottles that run your grill, patio heater, fish fryer, or small camping stove. You either swap an empty tank for a filled one at a kiosk or counter, or you bring your own tank in to have it refilled on the spot. Sarasota has 38 businesses offering this service, from hardware stores and gas stations with exchange cages out front to dedicated propane dealers who fill tanks by weight at their own stations.
The two methods matter for your wallet and your fill. Exchange is fast and available almost anywhere, but you're getting whatever tank is in the cage, usually filled to about 15-17 lbs rather than a full 20, and you're paying for the convenience. Refilling your own tank at a propane dealer's station generally gets you a more complete fill (by weight, not by guesswork) and a lower per-gallon cost, but it means driving to a location with a fill station and waiting a few minutes on-site.
When picking a provider, look for a station that fills by weight on a certified scale, checks your tank's certification date (tanks need recertification every 12 years), and inspects the valve and gasket before filling. A provider that turns away a rusted, dented, or out-of-date tank rather than filling it anyway is doing you a favor.
Our scoring weighs proximity, hours, price transparency, and how consistently a location actually has tanks in stock or staff available to fill on demand.
